Common questions
Source: NHTSA, 49 CFR 579.5Is Land Rover Discovery_N869_21FEB25 a recall?
No. A manufacturer communication is a manufacturer communication filed with NHTSA under 49 CFR 579.5; a safety recall carries an NHTSA campaign number (two digits, a letter, six digits) and a federal duty to repair for free. Check the vehicle’s recalls by VIN at nhtsa.gov/recalls, or on its page here.
Is the Discovery_N869_21FEB25 repair free?

The manufacturer filed it against 4 model years: 2023 Land Rover Discovery, 2022 Land Rover Discovery, 2021 Land Rover Discovery, 2021 Land Rover Discovery Sport. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
